The present invention relates to a finger grip (1) arranged to be connected to a syringe barrel having a plunger and a plunger rod for driving said plunger. The finger grip comprises a body having a lower side with finger supporting surfaces (13) for supporting fingers of a user during handling and an engagement member (5) being moveable between an inactive position where the engagement member is arranged not to engage with the plunger rod of the syringe barrel and an active position where the engagement member is arranged to engage with a grooved surface on the plunger rod of the syringe such that feedback is given to a user as the plunger is moved relative to the finger grip. An activation member (7) for moving the engagement member from said inactive position to said active position is built-in into the finger grip.

A syringe (1) is provided with a tube (2), a plunger rod (3), and a plunger rod head (4). The plunger rod head (4) has a first surface (41) and a second surface (42). A finger grip component (5) is provided as a one-piece body attached to the tube (2), and includes an injection finger support surface (61) arched in a direction perpendicular to the longitudinal axis (A) with a first curvature for co-operative association with the first surface (41), and an aspiration finger support surface (62) arched in a direction perpendicular to the longitudinal axis (A) with a second curvature for co-operative association with the second surface (42).

The present disclosure relates to an injection device, in particular a micro dose injection device such as, for example, an ophthalmic injection device. An example device comprises a rotatable plunger; a solution receptacle having a first end configured to slidably receive the rotatable plunger and a second end configured to dispense solution contained in the solution receptacle; a first stop member configured to prevent the rotatable plunger from being slidably displaced to a second position while the rotatable plunger is at a first position and in a first orientation; and a second stop member configured to prevent the rotatable plunger from rotating in a first direction about the first axis while the rotatable plunger is at the first position and in the first orientation, wherein slidably displacing the rotatable plunger from the first position to the second position dispenses a quantity of the solution contained in the solution receptacle.

A syringe holder includes: a barrel body that holds a syringe; a holder opening; deformation promoting portions; and radial movement-restricting portions. The radial movement-restricting portions are provided close to the deformation promoting portions. Being brought into contact with first portions, the radial movement-restricting portions restrict the syringe from moving in a radial direction with respect to the barrel body.

According to some embodiments, a syringe may include a barrel; a delivery conduit; a plunger seal disposed within the barrel; and a plunger rod assembly affixed to an end of the barrel, the plunger rod assembly including a first plunger rod component comprising a first linear gear, a second plunger rod component disposed at least partially in the barrel and engaged with the plunger seal, wherein the second plunger rod component comprises a second linear gear, a first rotational gear having a plurality of gear teeth for engaging the first linear gear, and a second rotational gear having a second plurality of gear teeth for engaging the second linear gear, wherein the first rotational gear is coupled to the second rotational gear such that translation of the first plunger rod component causes translation of the second plunger rod component.

An injection system can have a Syringe Dose and Position Apparatus (SDPA) mounted to a syringe. The SDPA can have one or more circuit boards. The SDPA can include one or more sensors for determining information about an injection procedure, such as the dose measurement, injection location, and the like. The SDPA can also include a power management board, which can be a separate board than a board mounted with the sensors. The syringe can also include a light source in the needle. Light emitted from the light source can be detected by light detectors inside a training apparatus configured to receive the injection. The syringe can have a power source for powering the sensors and the light source. The SDPA and the power source can be mounted to the syringe flange.

An accessory for an injection device having a safety shield and at least one flange adapted to allow a user to grip the injection device and a syringe sheath moveable relative to the at least one flange from a pre-injection position to a locked-out position. The accessory comprises a body portion comprising a recess adapted to receive the safety shield of the injection device and a slot adapted to receive the at least one flange of the injection device.

An apparatus includes a housing, a carrier, and an expandable assembly. The housing defines an opening configured to selectively place a gas chamber of the housing in fluid communication with an exterior volume. The carrier is movably disposed within the housing and is coupled to a medicament container. A proximal surface of the carrier defines a portion of a boundary of the gas chamber. The expandable assembly has a first member and a second member. The first member is coupled to an elastomeric member disposed within the medicament container, and the second member includes a valve portion. The expandable assembly transitions from a collapsed configuration to an expanded configuration when the elastomeric member moves within the medicament container. The valve portion moves relative to the opening when the expandable assembly transitions from the first to the second configuration, placing the gas chamber in fluid communication with the exterior volume.

The present invention relates to a finger grip (1) arranged to be connected to a syringe barrel having a plunger and a plunger rod for driving said plunger. The finger grip comprises a body having a lower side with finger supporting surfaces (13) for supporting fingers of a user during handling and an engagement member (5) being moveable between an inactive position where the engagement member is arranged not to engage with the plunger rod of the syringe barrel and an active position where the engagement member is arranged to engage with a grooved surface on the plunger rod of the syringe such that feedback is given to a user as the plunger is moved relative to the finger grip. An activation member (7) for moving the engagement member from said inactive position to said active position is built-in into the finger grip.

The present specification relates to a subassembly for a drug delivery device, the subassembly comprising: a housing adapted to contain a drug container with a needle, a cap, and a spacer, wherein the housing has an inner surface forming a cavity configured to retain the drug container, wherein the cap is configured to be releasably connected to the housing, and wherein the spacer is arranged between the cap and the housing.
